sanding three stage paint

Hey everyone,

I'm about to spray color on my nova. It's a three stage paint - base,metallic, and clear. I want to know if I should plan to color sand in between the base and metallic coats, or spray the base and go directly to the metallic and then color sand.

Thanks!
Chris

Don't touch the base or mid coat, go right to clear !!!!!!!!!!!!
If ya do have to sand either 1, dust more base or mid coat, but be careful.
Tri coat is not for the faint of heart novice.

I'm a novice but not faint of heart. Ok, so unless I have a major disaster while doing the base and mid coats, go straight to the clear?

The only "problem" will be with the candy style midcoat.
You want a VERY CLEAN enviroment to spray this in as repairs at THIS stage are difficult to say the least.Base,no problem,Clear,No problem.
You get trash or serious nibs in the midcoat and it's a real PITA to deal with.
After spraying base,change the masking and if you used plastic,toss it and remask.I will double mask on these style jobs and just pull the base session off and go on.Most trash comes from either masking or YOU so,suite up accordingly and after the base flashes off WELL,Lightly tac it off after the remask/removal to remove dust and nibs.Wet the floor down carefully or vacume BEFORE tacking to remove the o'spray from the base.Whe your SURE you have most of the debris gone,get to the midcoat which may require some gun adjustment and settings changes to spray it "right".Likely,a little lighter on the fluid as you want a good pattern but coverage should be on the light side in order to achieve the proper tonage for the final color achieved.Remember,It's always easier to ADD then REMOVE and you need GOOD lighting to achieve this part and "if" it's a little light in coverage at spots,you can always dust the color back in to blend it right.I don't know what line your spraying but having a qt of the lines binder or an intercoat clear can work this out.You can cut the midcoat starting with a 50% reduction with it,Dump what's in the gun or mix more straight and add the .5 depending on amount previous and spray light coats to blend it in completly.Once it's flashed good,if possiable,roll it out in the Sun and scrutinize it WELL.Looks good,Clear the thing.Otherwise,go back and blend the midcoat where necessary and "if" it's close but still not right,Recut you midcoat with the binder or intercoat another 50% and reblend.
